[ Upstream commit 4fade8329ab2be2b902fce8db3625fd12234b873 ]

The mtk-smi driver can now be built as a loadable module, but
this leads to a build time regression when the drivers that
depend on it are built-in:

aarch64-linux-ld: drivers/media/platform/mtk-mdp/mtk_mdp_comp.o: in function `mtk_mdp_comp_clock_on':
mtk_mdp_comp.c:(.text.mtk_mdp_comp_clock_on+0x54): undefined reference to `mtk_smi_larb_get'
aarch64-linux-ld: drivers/media/platform/mtk-mdp/mtk_mdp_comp.o: in function `mtk_mdp_comp_clock_off':
mtk_mdp_comp.c:(.text.mtk_mdp_comp_clock_off+0x12c): undefined reference to `mtk_smi_larb_put'

Add a dependency on the interface, but keep allowing
compile-testing without that driver, as it was originally
intended.
